To @ZZ 'wh/0711, t 71u03/ concern:

Beitknown thatLMIcHAELHl/ICINERNEY, a citizen of the United States, residing at Mc- Keesport, in the county of Allegheny, State` of Pennsylvania, haveinvented or discovered certain new and useful Improvements in Col-` umns or Poles, of which the following is a specification, reference being had to the accompanying drawings, in which* zo Figure l indicates an elevation of my improved pole for supporting electric Wires for street-railways, tre. Fig. 2 is a transverse section of the same. Fig. 3 is an elevation, partly in section, of the interior supportingx5 frame.

My invention relates to improvements in supporting-poles for electric conductors and street-railway lines; and my object is to produce a simple, cheap, and etcient pole for zo such purpose.

Incidentally the construction of my improved pole avoids excessive weights therein and enables the production of a pole of great rigidity and strength and to this purpose my invention consists in the novel construction,

combination, and arrangement of parts hereinafter described, reference being had to the accompanying drawings, which form a part of this specification, in which like reference 3o characters indicate like parts Wherever they occur throughout the several views thereof.

Referring to said drawings, l is a pole comprising a series of sections d. The said sections are formed of comparatively-light sheet metal or boiler-iron and preferably tapered from the base to the top, as shown in the drawings. The interior of saidv hollow pole is provided with a skeleton' frame 3, which tapers correspondingly to the exterior shell of the pole.

4o The said frame comprises vertically-disposed angle-pieces 4. 4, riveted or otherwise suitably secured to the interior of the shell, diagonally-disposed bars 5 5, secured in any suitable manner to said angle-pieces, and a centrally-disposed portion 6, to which the said bars 5 5 are also riveted or otherwise suitably secured, as at w.

The exterior of the pole may be painted with any suitable non-corrosive paint, and when it is desirable to provide steps on the 5o pole holes 7 may be provided in the sides and bars or rods S 8 inserted therein.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. A column or pole comprising an outer shell, and a frame within the shell comprising angle-irons extending vertically within the shell on opposite sides thereof, and secured to the shell, and independent, transversely- 6e disposed cross-bars connected at their ends to the angle-irons.

2. A column or pole comprising an outer shell, and a frame within the shell comprising angle-irons extending vertically Within the 65 shell on opposite sides thereofV and secured to the shell, and independent inclinedcrossbars having their ends secured to the angleirons and crossed over each other at their centers and there connected together. 7c

3. A column or pole comprising an outer shell, and inner skeleton frames arranged substantially at right angles to each other and having angular connections at their ends secured to the sides of the shell on the inside 7`5` face thereof and at their centers-connected to each otherA In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
